My current Debian Wheezy installation is an upgrade from Squeeze, so I was unprepared for what just happened: I’m doing a bunch of installs in between my other work, and I just got around to a traditional Wheezy desktop installation with the GNOME desktop using netinstall image. I was unprepared for the only GUI package manager to be GNOME Package Kit. No Synaptic Package Manager. Not even the "Sofware Center" ported from Ubuntu that shipped in Squeeze.
